[PSUBS-MAILIST] exotic steel

Wed Apr 29 19:41:46 EDT 2015

Hank,
When you say traditional material are you talking 516 grade 70 or HY100. If it is 516 grade 70 it becomes way overweight. If it is HY100 I have the sheets that Sean ran for me. The next question is do I want to aim for 1000 meters or 2000 meters? 
Thanks,
Scott Waters

Scott,
How over weight will your deep diver be if you use typical material to achieve your depth goal.  How much would you have to increase the dia to compensate for the extra weight.  Have you considered a buoyancy sphere to compensate for the over weight occupant sphere.
Hank
